RESUMO.-[Uma técnica simples e rápida de amostrar costelas para análises químicas e densitométricas por meio de biópsias em bovinos.] No presente estudo foi desenvolvida uma técnica para se obter, de forma rá-pida e simples, amostras da 12ª costela bovina por meio de biópsias. Avaliou-se a recuperação pós-operatória (durante 15 dias), o consumo de matéria seca (CMS) e o ganho de peso diário (GMD) de 36 novilhos Nelores, sendo nove animais controles e 27 submetidos à biópsia. A cada 30 dias biópsias de costelas foram realizadas em nove animais, usando uma furadeira elétrica acoplada a uma serra-copo com uma broca-guia de 3mm de diâme-tro. Esta técnica de biópsia permitiu obter amostras ós-seas de forma rápida, com o cirurgião operando sozinho e com os animais levemente sedados e em estação. Ao término do experimento (116 dias) o CMS e o GMD não foram afetados pelo procedimento cirúrgico. As amostras obtidas foram adequadas para exames radiográficos e subsequentes análises químicas. O conjunto de informações adquiridas com a técnica de biópsia de costelas permite aumentar a exatidão no diagnóstico da deficiência de fósforo em bovinos criados em pastagens e também realizar estudos sobre metabolismo ósseo em animais experimentais. We developed and evaluated a fast and simple method to obtain suitable bone samples for densitometry and chemical analysis through biopsies of the 12th rib of cattle. The postoperative recovery, dry matter intake (DMI) and average daily weight gain (ADG) was evaluated in 36 Nellore steers, nine of which were randomly selected for the control group and 27 others were rib biopsied. Every 30 days, rib biopsy was performed in nine steers, using a corded-electric pistol-grip drill coupled with a hole saw of a 3mm diameter pilot drill bit. This rib biopsy technique provided a suitable sample obtained in a fast way and allowed the surgeon to work alone with the animal slightly sedated and restrained in the crush. Dry matter intake (DMI) was not affected in biopsied animals. At the end of the experimental period (116 days) the average daily weight gain (ADG) was similar in the steers biopsied or not. The described method provided rib samples from cattle suitable for densitometry and chemical analysis of bone tissue without effects on health and performance. This information could greatly increase the accuracy for the diagnosis of phosphorus deficiency in cattle raised on pasture and allow the evaluation of bone metabolism in experimental animals.INDEX TERMS: Sampling method, chemical analysis, bone densitometry, rib biopsy, cattle, bone mineral density, Bos indicus, mineral deficiency, phosphorus.

Resumo: Em uma propriedade localizada na região nordeste do Estado do Pará foram analisadas alternativas de suplementação mineral para bovinos de corte, da raça nelore, machos, com idades entre 18 e 20 meses e pesos de 299,5 a 308,5 kg. Foram avaliados o custo benefício, os valores dos minerais no fígado e nas costelas e o ganho de peso médio diário dos animais submetidos aos diferentes tratamentos. O estudo foi realizado durante seis meses (março a agosto de 2012), no período de ótima oferta de pastagem. Foram utilizados 60 bovinos, divididos em três grupos de 20 animais em delineamento experimental inteiramente casualizado. O Grupo 1 foi suplementado com uma mistura mineral seletiva (MMS) composta por 25kg de NaCl, 50kg de fosfato bicálcico,190g de sulfato de Cobre, 60g de sulfato de Cobalto e 15g de selenito de sódio; essa mistura continha, em um quilograma, 133g de Na, 123g de P, 631 mg de Cu, 167mg de Co e 9 mg de Se; essa mistura foi proposta com base no prévio diagnóstico clínico-nutricional do rebanho. O Grupo 2 foi suplementado apenas com NaCl (Grupo controle) e o Grupo 3 recebeu uma mistura mineral comercial (MMC), rotineiramente utilizada na fazenda, contendo, em um quilograma, 130g de P, 220g de Ca, 18g de Mg, 36g de S, 6.000mg de Zn, 1.500mg de Cu, 2.000mg de Mn, 200mg de Co, 90mg de I e 36mg de Se. O melhor custo benefício foi obtido com a mistura mineral seletiva. A pastagem não contém Co suficiente para atender as necessidades dos bovinos do grupo controle, mas foi capaz de suprir as necessidades de P, Cu, Zn e Se durante os cinco meses do experimento.

“…In addition, the research and extension group in Clinical Medicine of Large Animals of the Federal University of Pará, Campus Castanhal, has been studying and diagnosing spinal fractures in animals with marked phosphorus deficiencies associated with neurological clinical signs in cattle and buffaloes (Peixoto et al 2005, Barbosa Neto et al 2007, 2021, Pinheiro et al 2011, Malafaia et al 2014, Bomjardim et al 2015. Therefore, the objective of this study was to perform a retrospective study characterizing the clinical-pathological conditions caused by CNS compressive lesions in buffaloes.…”

This study describes, through a retrospective study, the epidemiological and clinical-pathological findings of compression in the central nervous system (CNS) of buffaloes. The study includes observations made in 15 animals from 1998 to 2021 by reviewing the clinical records of animals with compressive injuries of the CNS treated at the Veterinary Hospital of the Veterinary Medicine Institute of the Federal University of Pará. The animals treated with clinical signs compatible with CNS compressive lesions were subjected to general and specific clinical examinations of the nervous system. Blood samples were collected from four animals for complete blood counts, and cerebrospinal fluid (CSF) samples were collected from three animals for physical evaluation. Thirteen animals were necropsied. The age range of the affected animals ranged from four months to 11 years of age, with a greater frequency over age 12 months (80%, 13/15). The most affected vertebral segment was between T3 and L3 (60%, 9/15), followed by brain injury (20%, 3/15), the L4-S2 segment (13.3%, 2/15) and the C1-C5 segment (6.7%, 1/15). The clinical findings varied according to the location of the lesion. The necropsy findings revealed paraypophyseal abscess in the brainstem and vertebral body, subarachnoid hematoma, lymphoma and vertebral fractures. The performance of a thorough clinical examination of the CNS combined with the necropsy findings was important to characterize the clinical picture and to locate the cause and the affected CNS segments in the buffaloes studied. It is important to include CNS compressive lesions among the neurological diseases of buffaloes.
